The transmission of energy across the interface of a gold film with bulk sapphire has been studied using a metallic magnetic calorimeter. The transfer of energy by both high frequency and thermal phonons is found to be dependent upon the thickness of the gold film. For high frequency phonons the thickness dependence occurs when the size of the attenuation length in gold becomes comparable to the thickness. When the wavelength of the thermal phonons is larger than the thickness of the film, the density of modes of such phonons is altered from that of the bulk and the energy transmission is decreased.
